Amazon's websites each feature a slightly different selection of Tove Jansson books, both new and second-hand. The French site currently lists fairly few books, but French-language books can still be found on the Canadian site.

Ebay
Ebay is the best place to find rare and second-hand Moomin books. Recent listings have included copies of the 1957 Moomin 1 picture book, UK hardback first editions of Comet in Moominland and Moominvalley in November, and even books signed by Tove Jansson.

Abebooks
I discovered this site in autumn 2003, and it's pretty unique: It has a large and persistent selection of Moomin books. Currently (in November), prices range from $1.00 (for ordinary paperback editions) to $5,000.00 (for a signed Swedish first edition of Moomin, Mymble and Little My.

Places to visit offline

Moomin Museum in Tampere, Finland
This excellent site is a great guide to the musem dedicated to Tove Jansson in the Finnish town of Tampere. The museum is widely praised, and houses many original illustrations, seasonal exhibitions and 3D features including a five-storey model of the Moominhouse. One day I'll manage to visit this museum!

Moominworld in Naantali, Finland
The Moominworld theme park in Naantali is more commercial than Tampere's museum, and their rather flashy website reflects this. Reviews have said the park is good to visit with children, though recent postings on the Moominvalley message board have suggested that the non-commercial parts of the park are becoming neglected.

Publishers

Sort Of Books
Sort of Books is a relatively new UK publisher with a small selection which happily includes several titles by Tove Jansson!

Their site includes numerous resources and information about Tove Jansson and her work.

Schildts is the publisher of Tove Jansson's original Swedish works in Finland; they also publish books about the writer's life and work. Their site features a good summary of Tove Jansson and The Moomins.

Moomin Voices
Not exactly a publisher, but close: Moomin Voices is a site by Mika Pohjola devoted to his album of Tove Jansson's songs put to music. Sheet music, information about live concerts and clips are available on this site.

Merchandise

Arabia of Finland
I'm not a fan of the Moomin merchandise that gets produced these days - soft toys and so on. However, Arabia has produced some really nice mugs, plates and similar items featuring Tove Jansson's original Moomin illustrations, adapted by Tove Slotte-Elevant. You can't order on the site, but these items can sometimes be found in House of Fraser in the UK. Also in the UK, the Scandinavian shops
Shannon
(in Bath) and
Schiang
(in St Albans) both stock a great selection of Arabia and other Finnish products.

Zépé's Muminforschung
This recently-redesigned site is a fantastic resource for fans of Tove Jansson and the Moomins. It's in German so I don't understand all of it, but it's certainly still worth a visit for English speakers - it contains summaries of all books, information about picture books and comics, hypothetical timelines, a table of which characters occur in which stories, and much more.
